Abstract

Light metal piston for internal combustion engines, with bolt hubs supported on the piston cylinder head essentially by means of axial props, the end surfaces of which are externally in the direction of the bolt, have a smaller separation than that corresponding to the diameter of the piston cylinder head, with recesses by way of windows being provided in the piston cylinder cylinder which leave the bolt eyes free in the direction of the bolt, with whose edges the bolt hubs are propped up starting from its eyes, characterized in that the props, except in the areas adjacent to the sliding surfaces of the piston, they are found on the lateral surface of a cone stem with a taper angle of less than 110º.
